Why use dtMathFloorf to calculate tx1/ty1 (max_x/max_y) but not dtMathCeilf in dtTileCache::queryTiles

I tried to generate dtTileCache back from dtNavMesh, and found the obstacle not working in some case because dtTileCache::queryTiles return 0 result.

DId I miss any guarantees in dtTileCache?

I found I misused the borderSize cause this problem... The code is correct, never mind.
